SIG NAL-LANTERN.

SPEGXFIGATION forming part of Letters Patent No. 733,892, dated July 14, 1903 Application filed November 21, 1902. serial No. 132,248. (No model.)

To all whom it may concern.-

Be it known that I, PAUL ABRAHAM, a subject of the Emperor of Germany, and a resident of the city and State of NewYork, have invented certain-new and useful Improvements in Signal-Lanterns, of which the following is a specification;

This invention relates to signal-lanterns; and its primary object is to facilitate changing the color of the light given by the lantern, especially when the lantern is intended to exhibit one color of light at one side and a different color at another side.

Other objects will hereinafter appear.

In the accompanying drawings, Figure l is a side elevation of a lantern embodying my improvements. Fig. 2 is a sectional elevation taken on the line 2 of Fig. 3. Fig. 3is a sectional plan illustrating the body of the lantern and the slides and operating levers mounted therein. Fig. 4 is a sectional plan illustrating a modified form of the slide-actuating lever. Fig. 5 is a vertical section of a portion of the lantern, illustrating particularly the relation of the colored or white glass panes, the sashes in which theyare secured, and the frames in which the sashes slide up and down. Fig. 6 illustrates the connection of the finger-keys to the sash-operating levers and the manner in which the latter are mounted within the casing of the lantern. Fig. 7 is a perspective fragmentary view of the upper portion of the device illustrated at Fig. 4. Fig. 8 illustrates how one of the arms fixed upon the outer sash may be bent around the frame in which the inner sashslides. Fig.9 illustrates one of the finger-keys held in working position by means of a detent.

In the several views like parts are designated by like characters of reference.

The body 10 of the lantern contains,as usual, a lamp 11, held by catches 12, and near its bottom is provided with lenses 13 and 14 at right angles to each other for the usual purpose. Between the lens 13 and the lamp are disposed one or morevertical glass panes 15 16, which are mounted in sashes 17 18, one behind the other. and independently movable to a position of use or disuse. Each sash may consist of a lower ohannel-bar A for the reception of the lower edge of the pane, an upper parallel bar B, between the portions .the two on ter frames.

guideways, or they may be otherwise guided from a position of use to one of disuse. Between the other lens 14 and the lamp are also provided glass panes 26, mounted in sashes 27 28, the latter working between guide-strips 29, 30, and 31 upon one side, the last two forming a channel-bar, as shown, and strips 32, 33, and 34 upon the other 'side. The group of strips 22, 23, 24, 32, 33, and 34 maybe in the form of a single bracket secured to the inside of the lantern, as shown, and the same is true of each of the other groups of strips shown.

By preference the sash 17 is united to the sash 27 by means of upper and lower tie-bars 35, and the two sashes are thus made into a singleframe and may move up and down as a single piece, thereby to change the lights exhibited by both of the lenses 13 and 14. The sashes 18 and 28 are likewise united by tie-bars -36, forming the two inner sashes into a single frame. Thus the two inner panes may be moved together up or down as well as It will be seen that the sashes composing each frame are at right angles to each other. By this construction and arrangement the changing of the lights exhibited at the two sides of the lantern is facilitated. If desired, one or more similar frames may be added.

For convenience of operating the inner frame I fix arms 37 to the upper bar B of each of the sashes, said arms being parallel to each other, but projecting at an angle of forty-five degrees from said bars'B. Slots 38 in said arms are engaged by pins 39, provided upon tines 40 of a forked lever.v 41", said pins being axially coincident and said lever beingforked,

so as to clear the lamp and being fulcrumed.

lever the double sash is slid up or down, the slots 38 permitting the necessary play of the pins 39. For the same purpose the outer frame is provided with slotted arms 44, which at 45 are bent around the fixed vertical guides 21 and 31 and secured to the upper ends of the sashes. The slotted arms 44 may be engaged by pins 46, provided upon the free ends of levers 47, also fulcrumed by means of the pin 42. Said levers may be fast to said pin 42, and the latter may turn freely in the bracket and in the hole in the lever 41. Preferably the lever 40 41 is nested within the arms 47, as shown at Fig. 3, thereby contributing to economy of space. By operating the arms 47 the outer double sash 27 17 may be lifted or depressed. The levers may be operated in any suitable way, preferably by keys 48 49, mounted upon the tips of vertical sliding stems 50 51, which work in guides provided upon a portion 10 of the lanternbody, Fig. 9. At its lower end the key-stem 50 has a pin-and-slot connection 52 with the sash-operating lever 41, While the lower end of the stem 51 is branched or forked and provided with pin-and-slot connections 53 to the levers 47, the latter operating as one piece. Said key-stems, it will be observed, are connected to the short arms of the levers, which are levers of the first order by preference, the sashes being operated in a downward direction, preferably by gravity, and being lifted downward by pressure upon the finger-keys.

Any suitable means may be provided for maintaining either or both of the double sashes in the elevated position of disuse; but by preference I employ latches 54 55, adapted to catch over the heads of the depressed keys,

.Figs. 2 and 9, said latches being mounted upon the outside of the lantern and controlled by a suitable spring or springs 56 and being also provided with releasing-arms 57.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is as follows:

1. A signal-lantern for railroad use, comprising a body, individual openings distinct one from another upon different sides of the body, and a plurality of sashes behind each opening; each sash being operatively connected to one of the sashes at a different opening so as to be movable therewith to a position of use or disuse; and means for guiding the connected sashes in their movements; so that by moving one set of sashes to a position of disuse and another set to a position of use, changes of signals may be efiected equal in number to the number of sashes in a set.

2. A signal-lantern for railroad use, comprising a body, individual openings distinct one from another upon difierent sides of the body, a plurality of sashes behind each opening, each sash being operatively connected to one of the sashes at a different opening so as to be movable therewith to a position of use or disuse; means for guiding the connected sashes in their movements; and differentlycolored glasses respectively mounted in the connected sashes.

3.
